Penny Press Puzzle Magazine- I love this magazine and have for many years.
They feature all kinds of puzzles. Each month they feature round 250 puzzles everything from crossword puzzles, anagrams, Sudoku, Kakuro, mazes, fill-ins, Crostic puzzles, syllacrostic, word seeks, logic problems, and dozens of other kinds of puzzles.
I also love that they will take their most popular puzzles and put several of each in each magazine and each one will be harder than the last one. This allows any level of puzzle fan to work these puzzles.
Sometimes Penny Press puts out magazines that contain all the same kinds of puzzles. For example you might see one thats all Sudoku puzzles. The nice thing about this company is they will send you tips on certain kinds of puzzles so if you are having trouble with, for example, the logic puzzles you write them and they send you tips on how to solve logic puzzles or you can visit their website for tips.
You can buy these magazines anywhere magazines are sold or they are available by subscription in the US and abroad. They also sell back issues in packs of 8 or 16 magazines.
Absolutely one of my favorite magazines of all time!
